It's interesting how all of this highlighted social divisions, even subtle ones that weren't much of an issue before, like well paid doctors and nurses and other medical staff that couldn't work from home, and had to take risks with their & their family's safety:
I know someone whose spouse is an EMT, and they basically has to quarantine him in the house to stay safe because they worked in an extreme outbreak hotspot. Even then, the EMT brought home COVID and the other spouse ended up in the hospital, all just before the vaccine became available. That person still hasn't fully recovered, even though they're otherwise a perfectly health non-risk-group person, still weakened enough that even a partial return to working in person is at least a few weeks away.
There's going to be research for decades just on all of the social impacts this has had on society.
The closest comparison I can think off-- though not perfect-- are the social and workforce changes that occured I'm the wake of WWII... Not to mention the failed attempt afterwards to put the genie back in the bottle of women in the workplace.
Strange, interesting, horrific times we're in.
